This is a free illustration of a rusty 10-yen coin. It’s perfect for spooky rituals like Kokkuri-san—a Japanese version of the Ouija board—where a coin guides the spirits across a sheet of paper. As for cleaning a real one? Some swear by lemon juice, others by mayonnaise or even ketchup. Personally, I’m team lemon juice. How about you?
